Finally, the course talks about the elimination of waste materials which cannot be digested by our bodies, as well as discussing the reticuloendothelial system. Whether you want to study the digestive system as part of a wider course of biological study or just to learn more about how our bodies work, this course teaches you how we turn food into the energy we need to survive, so make sure you start learning today.
